I bought a used 2006 HHR LT2 2.4L and did my first oil change last night. When I drained the oil out it appeared to be quite a bit of oil, the owner’s manual says it takes 5 quarts, it looked like 6 to me based of the level in my drain pan. So I put 5 quarts of M1 5w30 in it and backed it off the ramps and checked the oil. 1 quart low on the stick, I waited 5 min. checked it again. 1 quart low. Does any one have one of these that take 6 quarts? Or is it possible that this one has the wrong dip stick.
